The MN21T overpressure indicator is an essential device for industrial pressure safety, designed to prevent excessive build-up in silos and tanks. Combining precision and durability, it is tailored for facilities handling solids and liquids, ensuring uninterrupted operations while enhancing workplace safety.
Key Features
- Adjustable sensitivity from 200 to 1000 mbar
- Aluminium die-cast housing for extreme durability
- High protection against explosive dust and powders
- No power supply required for operation
- Versatile installation: vertical, horizontal, or oblique
Design & Functionality
The MN21T’s design integrates a sensitive diaphragm connected to a microswitch, which reliably actuates at set pressure levels. Its EPDM and stainless steel membrane ensures long-term functionality even in demanding environments. The single cable entry options allow easy integration with industrial monitoring systems.
Total Crossed Beams
The robust diaphragm design delivers consistent pressure detection across the entire measurement range, minimizing false triggers and ensuring operational reliability.
Beam Pitch Options
With adjustable sensitivity between 200–1000 mbar, MN21T allows precise calibration to match specific silo or tank requirements, offering maximum flexibility for industrial applications.
Intrinsic Synchronism
The indicator’s mechanical operation ensures intrinsic synchronism, making it ideal for explosive environments without external power. It maintains stability across temperature fluctuations from -40 °C to +85 °C.
Operational Advantages
- Reduces risk of overpressure incidents in industrial storage
- Simplifies maintenance with durable, power-free design
- Supports high industrial standards, including ATEX, IECEx, and UKCA certifications
- Safe for direct or indirect contact with food-grade materials
